NATURAL HISTORY NOTES 
April 1, 1915. — Another of the chameleons fell or threw 
itself down and killed itself ; the posterior half of the body went 
white immediately, and the poor creature never stirred again. 
Sometimes one will jump down six or more times in a single 
morning, and these two accidents must be due to their having 
fallen on their backs. When given a grasshopper the other 
day, it held the kicking fore-legs in its hand ; another that I 
had I gave five ant-lions, about four inches long, one after 
another, and with its hand it pulled off the wings before eating, 
in the most human fashion. 
A'pril 8 , 1915.— On the hillside by the P.W.D. workshops 
I caught thirteen lizards of five different species : a gecko 
under a stone, an agama under the roots of a tree, which 
subsequently proved to be a female with ten eggs in the oviduct ; 
nine striped skinks basking or under rubbish, and a very 
snake-like skink with highly polished scales in a termites’ 
nest under a huge stone. There were a number of very large 
Polydesmus millipedes by the river and a lot of blue dragon- 
flies. 
April 7, 1915. — The last three nights the 4 wait ’ note of 
the frogs has been less noticeable, and a croak like that of a 
bubble of water breaking on the surface has taken its place. 
I found that it is not made in the water ; in fact the greater 
number of cries come from the drenched grass, and by listening 
carefully it can be heard in the depths of the termite hills. 
Later I caught some of the handsome little frogs that are 
responsible ; they were males of Cassina senegalensis, which 
differ from the females by having an adhesive disc on the 
throat. They were answered from the ponds, probably by 
the females. 
I also caught specimens of Arthroleptis minutus, a little 
frog no larger than an English one when it emerges from its 
tadpole stage ; it grows no larger, of course. In swimming across 
the water it looks like a beetle, as it makes a strong backwater 
or rather cuts two ripples. 
April 9, 1915. — On nearing the edge of a wood in which 
I was, I saw through the leafy screen of bushes which concealed 
me, no less than eighteen buzzards ( Buteo desertorum), bowing 
and scraping to one another and stretching their necks almost
